Adaptive controller

(Note) EC series has their controller built-in themselves. See page 285 for further details on the built-in controller.

Important notes on selection

(1) The value shown for load capacity in "Main specification" refers to the maximum value. When enabling the power saving setting, the main specifications will change. For details, refer to "Payload table by speed/acceleration".
(2) Radial cylinder has a built-in guide. See page 377 for details on the radial load acting on the rod.
(3) Horizontal load capacity shown assumes an operation running with an external guide.
(4) Refer "Correlation of pressing force and current limit value" for further information on pressing motion. Pressing force shown are their standard value.
(5) It is necessary to limit the duty depending on the ambient temperature used. Refer to page 389 for further details.
(6) Safety measures may be required depending on the attachment orientation. Refer to page 379 for further details.
